| Event Text RADIOGRAPHY CAMERA SOURCE NOT FULLY RETRACTED
The following information was received via email:
"Radiographer failed to fully retract Se-75 source into QSA Model 880 camera while on a job site in Stratton, Ohio. No additional information regarding device or source is available at this time.
"Radiographer did not 'bump check' the source after retraction to make sure that the source was locked in the camera. He stated that he was using a survey meter as he approached the camera, but it slipped from his hand during his approach and fell to the ground. He stated that he did not verify proper operation after picking up the meter. He was approaching the camera from the rear and stated that he had not observed any reading on the meter. As the radiographer disconnected the guide tube, he noted that the source cable was still sticking out of the camera with the source. He stated that he turned the crank handle about 3/4 of a turn, at which time the source was retracted. The radiographer stated that he could not hear his alarming rate meter due to loud noise in the power plant where the work was being done. The radiographers pocket dosimeter (0 - 200 Mr) was reported as having gone off-scale.
"The licensee has estimated a whole body exposure of 1.8 R and an extremity dose to the radiographer's hand of between 3 R and 20 R. The licensee has shipped the radiographer's dosimeter for rush processing and expects to have results late Monday (4/12/10) or Tuesday. ODH [Ohio Department of Health] will conduct an investigation.
"NOTE: This report is being made as a precaution until the actual dose received by the radiographer is confirmed."

"This 60-day telephone notification is being made under reporting requirements specified by 10 CFR 50.73(a)(2)(iv)(A) and 10 CFR 50.73(a)(1).
"On 2/16/10 at 1122 EST, following maintenance activities on 'B' Emergency Safeguards Sequencer, Clearance Order 213623, was in the process of being lifted when an automatic start of 'B' Motor Driven Auxiliary Feedwater (MDAFW) pump occurred. Water flowed to all three Steam Generators resulting in an increase of reactor power by 0.1%. Isolation of Steam Generator Blowdown and Blowdown Sampling also occurred. The actuation occurred during work associated with replacement of relay 2-55/1163 which was installed incorrectly in the "B" Sequencer cabinet. At the time of the event, all Steam Generator levels were normal. No actual condition existed that would require an automatic start of the "B" MDAFW pump and therefore this event has been classified as an invalid actuation.
"All equipment operated properly. The 'B' MDAFW pump was secured by operations at 1123 EST.
"This invalid actuation was entered into the corrective action program as [Harris Nuclear Condition Report] NCR 381672.
"The safety significance of this event is considered to be minimal. The 'B' MDAFW pump started and operated normally and the 'A' MDAFW and Turbine Driven Auxiliary Feedwater (TDAFW) pumps were available.
"Immediate corrective actions were to secure the "B" MDAFW pump and restore Steam Generator Blowdown and Sampling."

| Event Text FAULTY MODULATION INDEX CONTROL CIRCUIT BOARD USED IN A POWER SUPPLY
The following is a summary of information received via fax:
"UCI [United Controls International] personnel witnessed system level functional testing of three [Modulation Index Control] MIC circuit boards in a spare unit on March 9-10, 2010 at the PSEG Nuclear LLC training center as part of the dedication process. Initially, the boards were accepted based on the test results but later irregularities were noticed on the output side of another card (reference oscillator) in the system. The Original Equipment Manufacture (Thomas & Betts) began troubleshooting the issue and determined that two resistors (R336 and R347) had one leg each terminated in the wrong location. Subsequent repair and testing confirmed this to be the issue and that once corrected, the irregularities were gone.
"The affected licensees are PSEG Nuclear LLC - Salem and Hope Creek Nuclear Generating Stations." |

"At 1703 EDT on Wednesday, April 14, 2010, the Pilgrim Nuclear Power Station (PNPS) determined that the in-plant paging/notification systems used to notify the Emergency Response Organization (ERO) were not functioning as designed or required by the Emergency Plan. Specifically, the in-plant notification system which is comprised of the Computerized Automated Notification System (CANS) and back-up system (BEEPS) could not be determined to function reliably or consistently during an Emergency Plan drill or event.
"Compensatory measures exist to contact members of the ERO by procedure via call-trees through the operations and security organizations at the site. Immediate actions are being taken to restore the system to functional status working with the service provider for the in-plant paging/notification systems.
"It cannot be determined at the time of this notification as to when the system will be restored to full, functional status.
"The licensee has notified the NRC Senior Resident Inspector." |

"The licensee notified the State of Minnesota Department of Natural Resources and the Minnesota Pollution Control Agency (MPCA) at 1620 CDT of a fish kill that occurred during a change to the plant circulating water system. Approximately 300-400 fish were found dead in the discharge canal during inspections related to a Zebra Mussel Treatment in progress. The fish included carp, green sunfish, bluegill, carpsuckers, and gizzard shad. The cause appears to be related to temperature changes in the canal as the external circulating water system was manipulated to achieve the 82-84 deg (F) condenser inlet temperatures needed for the treatment and a reduction in plant blowdown flow to the river required by the site discharge permit. The dead fish were contained in discharge canal due to a net that was deployed on Monday in preparation for zebra mussel treatment conducted today (treatment started at 1030 am). Fish in the discharge canal have been dead for 12 to 24 hours. The fish kill is unrelated to the zebra mussel treatment mulluscide addition and did not extend to state waterways.
"During the Zebra Mussel treatment, detectable mulluscide was found at the sluice gates to the Mississippi River at 1607 and the chemical addition was stopped The chemical is normally neutralized by addition of clay prior to reaching the sluice gates. The 1607 and 1620 samples at the sluice gates showed 0.6 ppm and 0.8 ppm of CL-2005 mulluscide and the 1730 sample had returned to non-detectable. The plant notified the Minnesota Department of Emergency Management of the chemical release at 1856, event number 110570. The MPCA will be notified during business hours tomorrow.
"A news release is not planned."
The licensee notified the NRC Resident Inspector. | |
